RPCEmu has been ported to the Mac OS X platform, allowing RISC OS 4 to run alongside Apple’s shiny desktop. An experimental port of the open source RiscPC emulator was checked into its source code repository over the weekend after the emulator was adapted to run on Apple computers that use PowerPC processors. The port can run RISC OS 4 and 3.7 with mouse and keyboard support. The emulation of IDE hard discs and higher resolutions needs further testing, and the user interface needs more work. The emulator manages around 5 MIPS on a modest 800MHz G4 iBook – which makes the desktop fairly usable.
